Automounting Samba shares using autofs

2018-02-19T00:28:27Z

Froelix: added forcing cifs version

'''Instructions:'''

1. Install autofs
$ sudo apt-get install autofs

2. Create map file with one mountpoint per line
# echo "desiredmountpoint -fstype=cifs,rw,username=mysmbuser,password=mysmbpwd,uid=myuser,gid=mygroup ://hostname/directory" >> /etc/auto.somename
To force a specific CIFS/SMB version use the following syntax
# echo "desiredmountpoint -fstype=cifs,rw,username=mysmbuser,password=mysmbpwd,uid=myuser,gid=mygroup,vers=2.0 ://hostname/directory" >> /etc/auto.somename

3. Add mapp file to master map (default timeout is 15min/900sec)
# echo "/mnt/anyexistingdir /etc/auto.somename --timeout 3600" >> /etc/auto.master

4. Restart the autofs daemon and check if it is working
$ sudo /etc/init.d/autofs restart

'''Notes:'''

* There might be some troubles resolving the hostname of the Samba server. Using the IP address instead of the hostname helped in my case.
* For more details regarding autofs, see [https://help.ubuntu.com/community/Autofs here].

Setting up SSH key authentication on Linux/UNIX

2016-08-31T14:27:46Z

Froelix: added hint to ssh-copy-id

'''Create the ''.ssh'' directory on the server (if it doesn't exist yet):'''
$ mkdir ~/.ssh
$ chmod 700 ~/.ssh

'''On the client run the following commands:'''<BR>
(Don’t enter a passphrase unless you want to type it every time you want to use the key)
$ ssh-keygen -t dsa
$ chmod 700 ~/.ssh
$ chmod 600 ~/.ssh/id_dsa
$ chmod 644 ~/.ssh/id_dsa.pub
$ scp ~/.ssh/id_dsa.pub <server hostname>:~/.ssh/

'''And on the server run these commands:'''
$ cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys2
$ chmod 600 ~/.ssh/authorized_keys2

'''Alternative to copy ssh id to server:'''
$ ssh-copy-id -i .ssh/id_rsa.pub <user>@<server hostname>

'''More information (Solaris):'''

SSL error with Citrix ICA client on Linux

2016-05-12T20:34:40Z

Froelix: added page

'''Problem:'''
* The Citrix ICA client does not connect to your corporate network.
* After launching the client it displays the following error message:
You have chosen not to trust “<CA which is used by your corporate network>”, the issuer of the server’s security certificate (SSL error 61).

'''Solution:'''
* The Linux version of the Citrix ICA client brings only a small set of root CAs which are trusted.
* Add the additional CAs which are required by copying the certificates to the following directory:
sudo cp <AnyCA.crt> /opt/Citrix/ICAClient/keystore/cacerts/
* Alternatively create symlink to the system ca-certificates:
sudo ln -s /usr/share/ca-certificates/mozilla/* /opt/Citrix/ICAClient/keystore/cacerts/
* Finally run the following command to rehash the certificates and you should be fine...
sudo c_rehash /opt/Citrix/ICAClient/keystore/cacerts/

'''Note:'''
* For more details, see [https://help.ubuntu.com/community/CitrixICAClientHowTo Ubuntu Help].

Application missing in ''Select Application'' dialog

2015-12-04T23:20:11Z

Froelix: added page

'''Problem:'''

You would like to open a file of a specific mimetype with a specific application and the ''Select Application'' dialog box (''Open with'' > ''Other application...'') does not show the desired application. Since Gnome 3 it is not possible anymore to manually enter a startup command.

'''Solution:'''

Check that a correct ''.desktop'' file for the application exists. This means the line ''Exec=...'' has to include ''%f''.
If this is not the case, copy the file from ''/usr/share/applications'' to ''~/.local/share/applications'' and add '' %f'' to the end of the ''Exec=...'' line.

MyRoundcube Calendar Plugin external calendars issues (CalDAV)

2015-02-06T22:37:48Z

Froelix:

'''Problem:'''
* MyRoundcube Calendar Plugin is not able to load external calendars which require username and password authentication.
* Adding a new CalDAV calendar gives the following error message:
''Failed to save changes.''<br>
''Failed to establish connection. Please check your data.''
* Roundcube setup:
** Roundcube 1.0.4
** calendar 19.0.49
** calendar_plus 4.0.37
** PHP 5.4.34
** MySQL 5.5.40

'''Solution:'''
* Issue might be the PHP variable '''open_basedir''' which is set.
* Either remove open_basedir, or change '''CURLOPT_FOLLOWLOCATION''' to '''false''' in the corresponding PHP file(s). In this case ''SabreDAV/lib/Sabre/DAV/Client.php'':
326: CURLOPT_FOLLOWLOCATION => false,

'''Note:'''

$ xinput --set-button-map "Logitech Unifying Device. Wireless PID:4026" 1 2 3 4 5 8 9 6 7

This example swaps the functionality of the scroll left/right buttons and the back/forward buttons.

'''Notes:'''
* To make the remapping permanent, create an executable script which executes the above command and add it to the autostart ([http://www.ubuntu-forum.de/artikel/50682/xinput-befehl-beim-startup-ausf%C3%BChren.html]).

'''Problem:'''
* The graphics of the gnome-shell (Grome 3) is very slow with ATI graphics adapter.

'''Solution:'''
* Add the following line to the bottom of the file ''/etc/environment'' and restart the session
CLUTTER_PAINT=disable-clipped-redraws:disable-culling

Encrypting root partition with decryption key on USB thumb drive

2013-03-10T17:49:36Z

Froelix:

'''Problem:'''
* Your root partition of Debian Linux is encrypted with DM-Crypt + LUKS.
* On each boot process you have to enter the password to decrypt the root partition.
* This description explains how to atomatically decrypt the root partition using a decryption key on a USB thumb drive.

'''Solution:'''
* Prepare a USB thumb drive with an ''ext3'' or a ''vfat'' partition and label the partition. In this example ''mypartitionlabel'' is used as label.
* Create a key file on the USB thumb drive which will be later used to decrypt the root partition:
dd if=/dev/urandom of=/media/usb/.keys/my.key bs=4k count=1
* Add the new created key to the LUKS partition (in this example the root partition is ''/dev/sda1'') that it can be used to decrypt it:
cryptsetup luksAddKey /dev/sda1 /media/usb/.keys/my.key
* Create a bash script (e.g. ''/root/getkey.sh'') which mounts the USB thumb drive and reads the key:
#!/bin/sh
modprobe usb-storage 1>&2
modprobe ehci-hcd 1>&2
sleep 1
mkdir /usb 1>&2
mount /dev/disk/by-label/mypartitionlabel -t ext3 -o ro /usb 1>&2
cat /usb/.keys/my.key
umount /usb 1>&2
* Add the following lines to ''/etc/initramfs-tools/modules'':
ext3
ehci-hcd
usb-storage
nls_cp437
nls_iso8859_1
vfat
* Adapt the ''/etc/crypttab'' to use the script which gets the key:
sda1_crypt UUID=24ef106a-6ed3-4d28-8355-e58c6621e9c1 none luks,keyscript=/root/getkey.sh
...
* Make a backup of the old ''initrd'' to be able to boot using the password as well:
cp /boot/initrd.img-3.2.0-4-amd64 /boot/initrd.img-3.2.0-4-amd64-password
* Update the ''initrd'' to use the key-script:
update-initramfs -u
* Update the grub bootloader to add the initrd backup to the bootmenu:
update-grub
* Reeboot and see if it works... ;-)
